Saudi Solar Permitting and SEC Connection Process: Step-by-Step Guide

Key Takeaways

• Grid interconnection for small-scale solar (1 kW to 2 MW) follows a standardized six-stage process administered by Saudi Electricity Company (SEC / Saudi Energy).
• All design submissions and formal filings must be executed by contractors and engineering consultants qualified through the Ministry of Energy SHAMSI platform.
• The utility installs the primary bi-directional meter at zero extra cost, while commercial systems above 100 kW must install a client-funded dedicated generation meter.
• Technical approval depends on passing two core checks during early stages: the site's contracted load ceiling and a 15% transformer rating cap.

How does the Saudi solar grid connection process work?

Connecting a rooftop photovoltaic system to the national electrical grid in the Kingdom of Saudi Arabia requires navigating a structured, legally binding workflow. Administered under the Water and Electricity Regulatory Authority (WERA) framework, the process balances consumer connection rights with utility network safety.

The regulatory framework establishes that power distributors must assist consumers willing to install solar by providing the technical information needed for feasibility studies and grid connection applications. However, to safeguard network integrity, consumers cannot connect hardware unilaterally.

Grid-connected solar PV systems between 1 kW and 2 MW fall under the Small-Scale Solar PV Framework, which provides a clear, standardized process. From initial feasibility to live energization, projects advance through six formal operational gates.

The Six Stages of SEC Solar Interconnection

```
Stage 1: Apply for Initial Solar Permit (Online Application)
│
Stage 2: SEC Site Survey & Approved PV Capacity Confirmation
│
Stage 3: Detailed Engineering Design Submission
│
Stage 4: Issuance of Solar Construction Permit
│
Stage 5: Installation Inspection & Bi-Directional Meter Setup
│
Stage 6: Signing Connection Agreement & Final Energization

Stage 1: Initial Permit Online Application

The connection journey begins digitally. The property owner or their authorized engineering firm must apply for an initial solar permit with an online application through the SEC e-services portal. This filing establishes property ownership, National Address coordinates, existing meter account numbers, and preliminary array sizing.

Stage 2: SEC Site Visit and Capacity Confirmation

Following online review, SEC visits the site and confirms the approved PV capacity. During this engineering field inspection, SEC technicians examine the service drop, main distribution panel, and local substation connection.

Two non-negotiable capacity rules are verified at this stage:

1. Contracted Load Ceiling: Installed capacity cannot exceed the contracted load at each site.
2. Transformer Capacity: Solar generation cannot exceed a transformer-level cap limiting solar capacity to 15% of the transformer rating.
3. Single Installation Boundary: A single installation may not exceed 2 MW.

If the requested system size violates either constraint, SEC issues a formal capacity reduction notice indicating the maximum permissible kilowatt rating.

Stage 3: Detailed Design Submission

Once capacity is locked, the engineering team prepares comprehensive electrical and civil schematics. The detailed design submitted for approval must include single-line diagrams, inverter protection relay settings complying with the Saudi Distribution Code, structural roof load certifications, and DC disconnect specifications.

Stage 4: Construction Permit Issuance

When SEC engineering review validates the design package, the construction permit is issued. This milestone formally authorizes the EPC contractor to commence physical rooftop mounting, inverter placement, AC cabling, and grounding installations.

Stage 5: SEC Pre-Commissioning Inspection and Meter Installation

Upon completion of physical construction, the contractor requests final testing. SEC visits the site again to inspect the installation and install the meter.

The utility inspects anti-islanding trip times, emergency DC shutoffs, and grounding electrode resistance. If testing passes, SEC technicians commission the revenue meter. The bi-directional main meter is installed at no additional cost by the Saudi Electricity Company (Saudi Energy).

However, larger commercial installations have a second hardware requirement: for systems above 100 kW, the client is responsible for installing a dedicated generation meter.

Stage 6: Connection Agreement Execution and Energization

With hardware certified and meters online, the connection agreement is signed, and final approvals are obtained.

This legal agreement governs billing terms under the national net billing framework:

• On-site self-consumption offsets grid import at retail tariff rates.
• Any surplus power exported to the grid is credited at 5 halalas/kWh.
• Utility billing records consumption with a meter reading cycle not exceeding 30 days.

Why is SHAMSI qualification mandatory for installers?

A property owner cannot hire an uncertified general electrical contractor to install a grid-tied solar system.

As part of the regulatory process, the Ministry of Energy has established a program to qualify contractors and consultants working on sub-2 MW systems. This program is administered through a digital platform called SHAMSI, which governs registration, compliance, and reporting.

Contractors must prove certified engineering staff, electrical safety credentials, and SASO-compliant equipment sourcing to maintain active SHAMSI accreditation. When an application is lodged on the SEC portal, the system requires entering the contractor's SHAMSI credentials. Submissions from unqualified firms are automatically rejected at intake.

What documentation must the asset owner prepare?

To avoid processing delays during Stages 1 and 3, facility owners should assemble required corporate and technical documents in advance:

• Valid commercial registration (CR) or national ID matching the electricity bill name.
• Title deed or documented landlord lease agreement authorizing rooftop modification.
• Recent SEC electricity bill showing account number and contracted kVA load.
• Architectural layout of the roof showing equipment clearances and access pathways.
• Datasheets for inverters and modules demonstrating SASO compliance.

By adhering to this established workflow and partnering with accredited professionals, residential and commercial consumers achieve seamless interconnection and rapid system energization.
